I think that, regardless of how "good" the aikido in the video may be, it is still very helpful to experience what others in the art are doing. I certainly can't judge the effectiveness of the techniques, but I find it very useful to see what others are doing so that I can make comparisons with what I'm learning. The judgement of "good" or "bad" and even "ass-kickingly street effective" is for each person to make on their own. Then after you've been exposed to more learning you can go back and smile at how foolish you were, and then do so again and again; that is the nature of learning afterall. Thank you very much for the link.
